Methionine requirements for meat type quail during the growing phase (7-42 days of age) were estimated in a completely randomized experimental design. The treatments consisted in a 2×6 factorial combination (two genetic lines and six methionine level in the diets: .73; .79; .85; .91; .97 and 1.03%). The quail were fed ad libitum. The traits recorded were body weight (BW), weight gain (WG), feed consumption (FC), feed: weight gain ratio (FGR). Significant effects of genetic line by methionine interaction were observed for all traits recorded from 22 to 42 days of age and for the total period. The methionine effect was quadratic for BW42 and WG742 for line EV1 and the maximum performances for both traits were observed for quails fed .88% methionine level diet. The genetic line by methionine interaction suggests genotypes need to be evaluated within level of methionine in selection program of quail.
